+* Before this update, the vSphere platform configuration lacked a validation check to prevent the simultaneous definition of both a custom virtual machine template and a `clusterOSImage` parameter. As a consequence, users could provide both parameters in the installation configuration, leading to ambiguity and potential deployment failures. With this release, the vSphere validation logic has been updated to ensure that template and `clusterOSImage` parameters are treated as mutually exclusive, returning a specific error message if both fields are populated.

+
+* Before this update, a race condition occurred when multiple reconciliation loops or concurrent processes attempted to add a virtual machine (VM) to a vSphere Host Group simultaneously due to the provider lacking a check to see if the VM was already a member. Consequently, the vSphere API could return errors during the cluster reconfiguration task, leading to reconciliation failures and preventing the VM from being correctly associated with its designated zone or host group. With this release, the zonal logic has been updated to verify the VM's membership within the target host group before initiating a reconfiguration task, ensuring the operation is only performed if the VM is not already present.
